Reaction Engines, a U.K. space company, has begun testing its high-Mach propulsion technology in a critical U.S.-based trial, as it looks to make more of an impact in the United States.

The company announced Monday that it has been working on a series of tests conducted with the Air Force Research Laboratory (AFRL) and the US Department of Defense. Reaction Engines has been working as part of a Foreign Comparative Testing (FCT) program. The FCT Program is administered by the Directorate of Defense Research and Engineering for Advanced Capabilities and is focused on the discovery, assessment, and testing of leading foreign technology with the potential to satisfy U.S. Defense technical demands.

The program seeks high Technology Readiness Level (TRL) technologies that could rapidly and economically satisfy current and emerging requirements.

“I am so proud of the innovation and drive evident in this combined Reaction Engines and Government team and I know they will keep performing now that the heat is on,” Adam Dissel, President of Reaction Engines US, said in a statement.
